A triangle can be rotated through any angle of your choice!An equilateral triangle has rotational symmetry of order 3, which means that a rotation of 120 degrees (or multiples) will bring it back to the same orientation. All other triangles have rotational symmetry of order 1: that is, you have to rotate them a full circle (360 deg) before they look the same.
A vertical line that passes through 7 and 2 is your face.
The cross section will be a triangle with base 2 feet and a vertical height of 9 feet.
If one of the three interior angles is 90 degrees then it is a right triangle.
Cylinder
The Isosceles triangle only has one possible line of symmetry; and that is through the vortex, AKA: The middle, in a vertical line.
Twice as large

Find the midpoint of a side and join it to the vertex opposite. That is a median and it divides the mass of a triangle in two halves. Each triangle has three medians. However, there is no reason for a bisector to go through a vertex - it can be a straight line through any point in the triangle. In such a case drawing the bisector analytically is likely to be beyond the skills of most geometry students. There is, though, a very simple practical solution. Cut out a copy of the triangle on a uniform lamina. Suspend it vertically by a pin through the required point. Then the vertical line through that point (use a plumb line) is the bisector of the triangle through that point.

For a right cone, it is a hyperbola which becomes and isosceles triangle when the section passes through the apex.

A vertical line that passes through 7 and 2 is your face.
Rotated about a line on the surface ? I = Mass * radius2 . Rotated about a line through the centre : I = (2 * mass * radius2) / 5
What is the equation of the vertical line passing through (-5,-2)
Yes, all of his voyages passed through the Triangle.
